汽车中叶板零件冲压工艺与冲模设计(任务书,开题报告,外文翻译,论文说明书11000字,CAD图13张)
摘要：模具是工业产品生产用的重要工艺设备，模具工业已是工业发展的基础，许多新产品的开发和研制在很大程度上都依赖与模具的生产。可以预言，随着工业生产的不断发展，模具工业在国民经济中的地位将日益提高，并在国民经济发展过程中发挥越来越重要的作用。在冲压零件的生产中，合理的冲压成形工艺、先进的模具、高效的冲压设备是必不可少的三要素 。
 本文介绍了止动件冲压模具的设计，先介绍了对工件进行工艺分析和模具设计的要点，然后介绍了模具设计的思路，模具的主要结构和主要零件的设计。最后确定了选用冲孔落料复合模。
本次设计绘图采用AotuCAD，以AotuCAD为计算机辅助制图工具，使用简单，方便快捷，而且有极强的图形处理功能，可以大大缩短绘图的周期，在国内使用的较广泛。

stamping process and die design of hinge Vol yen
ABSTRACT ：The mold was the important process unit which the manufactured products production used, the mold industry already is the industrial development foundation, many new product's developments and the development relied on to a great extent with mold's production. May predict that along with industrial production's unceasing development, the mold industry will enhance day by day in national economy's status, and plays more and more vital role in the national economy developing process. In the ramming components' production, the reasonable ramming forming craft, the advanced mold, the highly effective ramming equipment are the essential three essential factors. Ramming processing characteristic: Because the cold stamping processing has the above prominent merit, therefore obtained the widespread application in the volume production, holds the very important status in the modern industry production, is the defense industry and in the consumer industry production the essential processing method. this article introduced the lock ramming mold's design, introduced first carries on the process study and the mold design main point to the work piece, then introduced the mold design mentality, mold's primary structure and the major parts design. Finally had determined selects the punch holes to fall the material superposable die. the this design cartography uses AotuCAD, take AotuCAD as the computer auxiliary charting tool, the use is simple, facilitates quickly, and has the greatly strengthened graphic processing function, may reduce cartography greatly the cycle, in domestic use widespread.
